摘要： Rectangular or round spinning nozzle packs for extruding thermoplastic filaments each have both melt channels and orifices for the higher melting polymer compound and also melt channels with orifices through which is passed a polymer compound that melts at a temperature 5 to 50.degree. C. lower. Variously designed insulation channels thermally separate these melt channels, which are operated at different temperatures.

摘要： Synthetic plastic fibers are enhanced by inclusions therein of micro-polyester particles (4), preferably sized or otherwise optimized to enhance surface (10) characteristics (abrasion resistance, hydrophilicity, coating receptiveness, increase dullness), reduce UV degradation. The synthetic plastic matrix is preferably polyester but can be any synthetic plastic. The invention is preferentially implemented in multi-component fibers (e.g. core (6)-sheath (8) bi-component fibers (3)) with the inclusions entirely or primarily in one or some, but not all such components. The PTFE inclusions, sizing, concentration, morphology can be adjusted to optimize their enhancing effects, reduce costs and enhance throughput of fiber production. Co-inclusions can be made with the PTFE including anti-microbial and/or coloring agents and with synergistic effects.
摘要翻译：合成塑料纤维通过微聚酯颗粒（4）中的夹杂物增强，优选尺寸或以其它方式优化以增强表面（10）特性（耐磨性，亲水性，涂层接受性，增加的钝度），减少UV降解。合成塑料基质优选为聚酯，但可以是任何合成塑料。本发明优选地实施在具有所述夹杂物的多组分纤维（例如芯（6）-Sheath（8）双组分纤维（3））中，或者主要在一个或一些但不是所有这些组分中。可以调节PTFE夹杂物，尺寸，浓度，形态，以优化其增强效果，降低成本，提高纤维生产量。可以使用包含抗微生物剂和/或着色剂的PTFE和协同效应来制备共夹杂物。
